L aZZ 'w/w'l'n/ it ma 1 concern:

Be it known that I, DAvin M. 'inAIsUn, a citizen of the United States, residing at Mays, in the county of Bush and State of Indiana, have invented a new and useful Road-Yorking Machine, of which the following is a specification.

'This invention relates to road working machines and it relates more particularly to a tions of ST raping, spreading and grading the entire surface of aroad an be accomplished by passing over the road in only one direction, thereby produt ing a one way machine in distinotion to the ordinary two way machines by which the road is worked on one side by a "'machine passing in one direction and then the other side worked by the machine passing 1n the other direct on.

Another ob ect ol the invention is the provision of amachine which can be readily adapted for operating on old roads or in spreading, grading or leveling the material for new roads, and at the same time compacting the loose material so that the passing of the machine over the n: l p duces a smooth and finished surface in one operation. A still further object is the employment of a blade made of sections and H101} nted on the lcveler or other suitable part of the machine with mechanism for raising or lowering the blade and for adjusting the sections of the blade according to the character of the work to be done.

Another object is to provide a road working machine of the character referred to which is equipped with an operators seat arranged so as to permit the operator to convcnient-ly manipulate the operating 'l'l'lvtillttlh isms, in connection with a fore-carriage to which the machine is coupled and an additional forward seat provided for the driver.

'ith these ol'ijects in view, and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel featuresof construction and arrangement of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates certain of the embodiments of the in vention, Figure 1 is a front perspective view of the machine. Fig. 2 is a side elevation thereof. Figs. 2) and i are fragmentary detail views of the levelcr and adjustable blade extensions showing li'lmllllttl (onstructions.

Corresponding parts in the several figures are india alied throughout by similar charactors of reference.

Referring to the drawing, and more particularly to Fig. 2, A designates the road working machine having front wheels B of ordinary construction and provided with the usual draft device C. The machine A is provided with a tongue or reach 1 which is connected to the fOlWfLI'tl part of die machine in any suitable manner, and mountedon the reach or any other suitable part is a driver s seat :3. machine can he used with front wheels that may be imnporarily detached from a road wagon for the purpose, or if desired the front wheels may be a permanent part of the machine.

The machine A comprises an arched axle 8 on the ends of which are the wheels 4 and ct :lllOCi/Od with the vertical portions 5 of the axle are the members (3 to which the rear end of the tongue 1 is coi'incctod. The levelor 7 is suspended between the wheels 4 by means of the flexible elements or chains 8, the upper ends of which are attached to the divided shaft 9 supported. on the axle 3 by bearings 10. The two parts of the shaft 9 are adapted to be imlept-ndt-ntly rotated so that the chains 8 can be wound or unwound'in order to raise or lower the leveler 7 to vary the dematerial of the road as the machine passes thereover, and also to lift the loveler to 'a suitable height when the machine is trans ported from place to place, so as to be out of the. way of obstructions on the surface or road over which the machine is traveling The parts of the divided shaft 9 are separatelyactuated by worm wheels 11 moshing with worms l2 on the u n'ight shafts or posts 13 suitably supported on the axle 3, and on the upper end of the posts 13 are hand 1 wheels 14. The posts 13 are located on op- By providing a seat on the reach the gree of compacting or compressing of the too . wheels 14 simultaneously, or to tilt the latter by turning only one of the wheels.

. an adjusting posite sides ofthc middle of themachine and disposed between them and slightly at the rear thereofis the operators seat mount 1 ed on the axle 3. By arranging the parts in I this manner, the operator can actuate the hand wheels 14 by t 10 right and left hands to move the leveler bodily by turning both worm gearings between the posts 13 and shafts 9 serve as locks for holding the leveler in any adjusted position. movement of the cveler the same is provided with an n rigzht 16 adjacent each end which is movab 8.81am; the rear side of the axle/Sand held 1n place by the plates 17.

'lheiipper end ofthe uprights are provided with a plurality of apertures 18 for receiving the pins 19 that serve as sto s engaging on thetop side of the axle to limit the downward movement of the leveler. The leveler 7, which is preferably a ponderous body made of any suitable material and is arranged with its length transverse travel of the machine, has its under surface suitably shaped to give to the road-bed the proper finish and contour, the weight and shape of 'the leveler b'eine such as to tightly compress the ateri l ofwhich the road is made. The leveler also serves as a support s for spreading, scraping or grading b ade-s,

which may be of any desired construction. These-blades, of wh ch one form' 1s shown herewith, are secured to the front side of the.

leveler by means of suitable fasteners, such as one'or more screw bolts 20'. The lower edge. 21 of the blade is sha )ed according to the requirements of the wori; to be done. ()n the ends of the blade 20 are arranged extensions 22 which are used in the operation of scraping and grading old roads, so as to put them in good condition. These terminal sections 22'of the blade are pivotally connected at 23 to the forwardly and outwardly bent extremities 24 of the blade 20. Thesections 22 diverge in a forward direction and the loose material scraped wardlv and rcarwardly, so that the blade 20 will distribute the loose material for it to be acted upon by the leveler, thereby giving the j roper crown or slope to the road. The

lade extensions 22 are each provided'with means whereby the depth of cut or penetration'of the extensions-ca n be governed. Each adjusting means comprises a bell crank lever 24 fulcrumed at its elbow on a bracket 25 arranged on each member 6, and attached to the outer end 'of the forwardly extending arm of the lever is a link 26 that is connected at its lower end with the blade extension 22m one side of the machine. The lever 34 is. actuated by a screw :27 journaled in thebracket 28 on the axle 3 and threaded in a tapped opening 29 at the upper The i To guide the to the direction of end of the upwardly extending a rni of the lever. The screw 27 is provided withahand wheel 30 at its rear end so as to beiiwithiri convenient reach of the operator from the seat 15. The adjusting means for the blade extensions are arranged on opposite sides of the middle of the machine so that-they can E be separately actuated by both-. hands at a time. i sions from spreading apart, they are. held. in {proper position by means of chains'31 each 1 extending from the outer end of one exten sion 22 to the adjacent brace member 6 ofthe tongue 1. These chains permit the blade extensions to be adjusted about their pivots without interference and brace the same with justment. The ends of the eveler are con-J which serve to hold the leveler inj'pro'per relation against undue strains. a

The leveler 7 may be straight throughout connection with t 1e accompanying drawing, the advantages of the construction and of preciated by those the invention appertains, and, while'i have invention, to I now consi thereof, I desire to the apparatus shown have it understood that merely illustrative,
